High Dynamic Range Imaging with TDC-Based CMOS SPAD Arrays
Instruments, 2019 This paper investigates the use of image sensors based on complementary metal−oxide−semiconductor (CMOS) single-photon avalanche diodes (SPADs) in high dynamic range (HDR) imaging by combining photon counts and timestamps. The proposed method

High Dynamic Range Imaging by Perceptual Logarithmic Exposure Merging
International Journal of Applied Mathematics and Computer Science, 2015 In this paper we emphasize a similarity between the logarithmic type image processing (LTIP) model and the Naka–Rushton model of the human visual system (HVS).

Sparse signal recovery from modulo observations
EURASIP Journal on Advances in Signal Processing, 2021 We consider the problem of reconstructing a signal from under-determined modulo observations (or measurements). This observation model is inspired by a relatively new imaging mechanism called modulo imaging, which can be used to extend the dynamic range ...

High-capacity watermarking of high dynamic range images [PDF]
EURASIP Journal on Image and Video Processing, 2016 High dynamic range (HDR) imaging techniques address the need to capture the full range of color and light that the human eyes can perceive in the real world. HDR technology is becoming more and more pervasive. In fact, most of the cameras and smartphones available on the market are capable of capturing HDR images.

High Dynamic Range and Super-Resolution Imaging From a Single Image
IEEE Access, 2018 This paper presents an algorithm for high dynamic range (HDR) and super-resolution (SR) imaging from a single image. First, we propose a new single image HDR imaging (HDRI) method based on the Retinex approach and exploit a recent single image SR method ...

RADIANCE DOMAIN COMPOSITING FOR HIGH DYNAMIC RANGE IMAGING [PDF]
ICTACT Journal on Image and Video Processing, 2013 High dynamic range imaging aims at creating an image with a range of intensity variations larger than the range supported by a camera sensor. Most commonly used methods combine multiple exposure low dynamic range (LDR) images, to obtain the high dynamic ...

De-ghosting in High Dynamic Range Imaging Based on Intensity Scaling Cue
Advances in Electrical and Computer Engineering, 2020 A High Dynamic Range (HDR) image produced from a sequence of low dynamic range (LDR) images can contain motion artefacts (ghosting) if the scene contains moving objects.
